Mazda BT-50 2022 review: XS 1.9 dual cab - GVM test

Our test vehicle, with 1.9-litre four-cylinder turbo-diesel and six-speed automatic, has a list price of $42,590 plus ORCs. That’s in the ballpark of 4x2 rivals like Ford’s Ranger XL 2.2-litre Hi-Rider ($40,790) and Toyota’s HiLux Workmate 2.4-litre Hi-Rider ($42,795), but Mazda is offering drive-away pricing of $43,990 for ABN holders.

Although clearly focused on work duties with its 17-inch steel wheels, 255/65 R17 tyres and full-size spare, it’s not starved of desirable features either given that there’s LED headlights with halogen DRLs, adaptive cruise control, reversing camera, USB ports front and rear and benchmark safety.

A four-speaker infotainment system with steering wheel-mounted audio controls includes Android Auto, wireless Apple CarPlay and DAB+ digital radio. Unfortunately, it also shares the same infotainment screen as its D-Max SX equivalent, with the display shrunk to 7.0 inches surrounded by thick black borders. This downgrade serves no useful purpose other than a visual point of difference from higher-grade models that use the full screen.

It might say Mazda on the engine cover but underneath it’s pure Isuzu - and that’s a plus. The hearty Euro 5-compliant 1.9-litre four-cylinder turbo-diesel produces 110kW at 3600rpm and 350Nm between 1800-2600rpm. While that’s 30kW less power and 100Nm less torque than Isuzu’s more familiar 3.0-litre unit, our test vehicle has a low kerb weight and its diff ratio is slightly shorter to compensate for the lower engine outputs (see Driving).

 The Aisin six-speed torque converter automatic is a smooth-shifting and proven performer, with electronic control minimising gear-hunting on climbs and automatically downshifting on steep descents to assist with engine-braking. It also has fuel-saving torque converter lock-up on third, fourth, fifth and sixth gears and the option of sequential manual-shifting.

Like its D-Max donor, there’s no remote-controlled locking diff like some 4x2 Hi-Rider rivals, with the BT-50 relying instead on electronic traction control when rear tyre grip is compromised.

Mazda claims an official combined figure of just 6.7L/100km but the dash display was showing a much higher 12.2 when we stopped to top up the 76-litre tank after 355km of testing, of which about one third was completed with more than one tonne of payload.  

However, our number calculated from fuel bowser and tripmeter readings was only 8.5, which was lower than the dash reading but higher than the official figure. Even so, that’s pretty frugal for a big dual cab ute, so you could expect a lengthy ‘real world’ driving range in the high-800km zone from a full tank of diesel.

Our test vehicle’s relatively low 1865kg kerb weight is 70kg lighter than its 4x4 equivalent, which with a 3000kg GVM rating results in a mighty 1135kg payload limit. It can also tow up to 3000kg of braked trailer, but to do that the payload would need to be reduced by 500kg or half a tonne to avoid exceeding the 5500kg GCM rating, or how much it can legally carry and tow at the same time.

Alternatively, you could lower the trailer weight by that same 500kg to 2500kg and keep the maximum payload. Either way, these are practical numbers to suit numerous work applications, whichever way you arrange them.

The load tub, which on our test vehicle was fitted with a non-standard tub-liner, has a 1571mm floor length, 1530mm width (measured at the top), 490mm depth and 1120mm between the wheel housings. There are four load anchorage points and a handy step in the centre of the rear bumper for accessing the tub when the tailgate is closed.

Cabin storage includes a large-bottle holder and bin in the base of each front door and a closable compartment to the right of the driver’s knee for small items. There’s also an overhead glasses holder, upper and lower gloveboxes and a centre console with open tray at the front, twin small-bottle/tall cup-holders in the centre and small box at the rear with a lid contoured to double as a driver’s elbow rest.

Rear passengers get a large-bottle holder and small storage nook in the base of each door plus flexible pouches on the front seat backrests. However, there’s no fold-down centre armrest with cup holders, so no cup storage when travelling with only two in the back.

The rear seat base cushion has a 60/40 split and both sides can swing up through 90 degrees and be stored vertically if more internal load space is needed. Doing this also reveals two large underfloor compartments with lids which could be particularly useful for storing valuables out of sight.

We loaded 890kg into the load tub which with our crew of two equalled a 1040kg payload that was only 95kg under its maximum rating. The rear leaf springs compressed 80mm, which seemed excessive until we observed that there was still an ample 40mm of bump-stop clearance remaining.

As a result, there was no bottoming-out during our load test, which covered a variety of sealed and unsealed roads. The BT-50 maintained its composure with sure-footed handling and negligible effect on steering and braking. At highway speeds there was no gear-hunting on moderate gradients, with the six-speed auto downshifting decisively to fifth and sometimes fourth to maintain the set speed.

It also proved to be a competent climber on our 13 per cent gradient, 2.0km-long set climb at 60km/h, downshifting to third gear at 2250rpm to easily pull this load to the summit with plenty of accelerator travel remaining.

Engine-braking on the way down, in a manual-selected second gear, wasn’t as robust and required several firm brake applications to avoid exceeding the posted speed limit. However, this lack of retardation is typical of other smaller displacement (under 3.0-litre) turbo-diesels we’ve tested.

The BT-50 is covered by Mazda's five years/unlimited km warranty. Scheduled servicing every 15,000km or 12 months whichever occurs first. Minimum cost of $2085 for the first five scheduled services, which represents a total saving of $230 over the 3.0-litre version.
